True or False: The locking step of the double action revolver happens when the hammer is in the cocked position.

The statement is true. In a double action revolver, the locking step occurs when the hammer is in the cocked position. During this phase, the action of the revolver is designed to ensure that the cylinder is properly aligned with the barrel, which is crucial for accurate firing and safety. When the hammer is cocked, it indicates that the revolver is ready to fire, and the mechanism securely locks the cylinder in place, preventing any movement that might cause misalignment during discharge. This ensures that the revolver can operate safely and effectively, making it a fundamental aspect of its design and function.
